My understanding is that 4.x doesn't have support for SATA. 
Evidently, the developers have been focusing on 5.x, and the 
necessary changes are non-trivial and not straightforward to apply to 

>From what I've read, you'll need to use 5.x in order to get support 
for your SATA drives.

I ran into this problem under 4.9-RELEASE.  As a test, I booted from 
the 5.1-RELEASE CD and the SATA drives were properly detected, and 
not downgraded to UDMA33.

I've sort of been waiting for the official word that 5.x is ready for 
production usage before I run with it (the documentation still 
recommends that "conservative users" not upgrade).

Hope this helps.
